Current electricity refers to the flow of electric charges through a conductor. For current to flow, a closed circuit is needed consisting of a source of electricity, conducting wires, and a device powered by the electricity. Common sources of current electricity include batteries and generators, which use chemical or mechanical means to provide a continuous supply of moving electric charges through a circuit.
